Billable CodeBillable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
POA Exempt CodeThe Center for Medicare & Medicaid Services (CMS) requires medical coders to indicate whether or not a condition was present at the time of admission, in order to properly assign MS-DRG codes. This "Present On Admission" (POA) indicator is recorded on CMS form 4010A.
B91 is a billable ICD code used to specify a diagnosis of sequelae of poliomyelitis. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
POA Indicators on CMS form 4010A are as follows:
|Indicator||Meaning||CMS Will Pay CC/MCC DRG Costs|
|Y||Diagnosis was present at time of inpatient admission||Yes|
|N||Diagnosis was not present at time of inpatient admission||No|
|U||Documentation insufficient to determine if the condition was present at the time of inpatient admission.||No|
|W||Clinically undetermined. Provider unable to clinically determine whether the condition was present at the time of inpatient admission.||Yes|
|1||Exempt from POA reporting||No|
The ICD code B91 is used to code Poliomyelitis
Poliomyelitis, often called polio or infantile paralysis, is an infectious disease caused by the poliovirus. In about 0.5% of cases there is muscle weakness resulting in an inability to move. This can occur over a few hours to few days. The weakness most often involves the legs but may less commonly involve the muscles of the head, neck and diaphragm. Many but not all people fully recover. In those with muscle weakness about 2% to 5% of children and 15% to 30% of adults die. Another 25% of people have minor symptoms such as fever and a sore throat and up to 5% have headache, neck stiffness and pains in the arms and legs. These people are usually back to normal within one or two weeks. In up to 70% of infections there are no symptoms. Years after recovery post-polio syndrome may occur, with a slow development of muscle weakness similar to what the person had during the initial infection.
